SS welded tubes grade 310 Diameter 9.5mm X 0.9 mm thickness

SS welded tubes grade 310 Diameter 9.5mm X 0.9 mm thickness , Suppliers & Exporters in India.

We are top leading manufacturers, stockholders & exporters of Stainless steel (SS) welded tubes are a crucial component in many industries, from oil and gas to chemical processing, due to their strength, durability, and versatility. Unlike welded tubes, seamless tubes are made without any joints, making them more reliable in high-pressure and high-temperature environments. Their seamless construction eliminates weak points, making them ideal for demanding applications where safety and performance are paramount. Today, we'll focus specifically on SS seamless tubes made from Grade 310 stainless steel, with a 9.5mm diameter and 0.9mm thickness — a combination often requested for industrial use.

What is Grade 310 Stainless Steel?

Grade 310 stainless steel is a high-alloy austenitic stainless steel known for its exceptional resistance to corrosion and oxidation, particularly at elevated temperatures. Composed primarily of iron, chromium, and nickel, it stands out because of its high chromium content (around 25%) and nickel content (approximately 20%). These elements provide the alloy with its corrosion-resistant properties and excellent strength at high temperatures. This makes Grade 310 a go-to material in industries like heat treatment, petrochemical processing, and power generation, where high-temperature resistance is critical.

Understanding Welded Tubes

Welded tubes differ from welded tubes in their manufacturing process. While welded tubes are made by joining the edges of a flat metal sheet, seamless tubes are created from a single billet of metal, which is heated and extruded into the desired shape. The absence of a welded seam makes these tubes inherently stronger and more reliable. This is especially beneficial in high-pressure environments where any weak point could lead to failure. The seamless construction ensures uniform strength throughout the tube, enhancing its performance in critical applications.

Specifics of SS Welded Tubes Grade 310

SS Welded tubes made from Grade 310 offer a combination of strength, heat resistance, and corrosion resistance that few other materials can match. These tubes are specifically designed to withstand high temperatures while maintaining structural integrity. Additionally, their resistance to oxidation in both continuous and intermittent service at temperatures up to 1100°C (2012°F) makes them ideal for heat exchangers, furnace parts, and other high-heat environments. The 9.5mm diameter and 0.9mm thickness make this size particularly useful in various industrial applications where precision and reliability are key.

Importance of Dimensions in SS Tubes

When it comes to selecting the right stainless steel tube, dimensions such as diameter and thickness play a significant role in determining the tube's suitability for specific applications. A 9.5mm diameter tube provides a balance between size and strength, making it suitable for use in confined spaces or systems that require precision. The 0.9mm thickness ensures that the tube is lightweight yet strong enough to handle the pressures and temperatures encountered in industrial settings. These dimensions are popular in industries that require both flexibility and robustness.

Advantages of SS Welded Tubes with 9.5mm Diameter and 0.9mm Thickness

The combination of a 9.5mm diameter and a 0.9mm thickness is optimal for various applications, particularly in industries like chemical processing, power generation, and automotive systems. These dimensions offer several key advantages:
  • Lightweight Design: The relatively thin wall thickness of 0.9mm ensures that the tube remains lightweight, which is essential for applications where reducing overall weight is a priority, such as in aerospace and automotive industries.
  • Strength: Despite the thin wall, Grade 310 stainless steel provides excellent tensile strength and can withstand harsh operating conditions.
  • Heat and Corrosion Resistance: These tubes perform well in both high-temperature and corrosive environments, making them suitable for chemical plants and refineries.
